A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and standard deviation 2.60. What is the probability of randomly selecting a rod that is shorter than 22 cm

Answers

Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Step-by-step explanation:

Step(i):-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

[tex]Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15[/tex]

Step(ii):-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

             = 1-P(Z>1.15)

             =  1-( 0.5+A(1.15)

             =  0.5 - A(1.15)

             = 0.5 - 0.3749

             = 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Graph the inverse of the function, f (x) = ( x+ 2)^3-4

Show all work in finding the inverse.

Answers

Answer:

The inverse of this function is:

[tex]f(x) = \sqrt[3]{x + 4} - 2[/tex]

Step-by-step explanation:

To find the inverse function, we can simply swap x and f(x) and solve for the latter:

[tex]x = (f(x) + 2)^3 - 4\\x + 4 = (f(x) + 2)^3\\\sqrt[3]{x + 4} = f(x) + 2\\f(x) = \sqrt[3]{x + 4} - 2[/tex]

Lin's family has traveled 25 miles which is only 20% of the trip.
How far is the whole trip?
a.
5 miles
c. 100 miles
b.
125 miles
d. 250 miles
Please hurry

Answers

Answer: 125 miles

Step-by-step explanation:

We know that 25 miles is 20% of the trip.

20% is 1/5 of 100, so that means we will multiply the number of miles driven by the denominator of the fraction.

25 × 5 = 125 miles

The answer to the question is 125 miles.

Hello!

[tex]\large\boxed{2x - 8 = 7 - 3x \text{ and } 4(x - 1) = x + 5}[/tex]

We can go through each equation to solve:

1.

x + 3 = 4(x - 1) + 2

Distribute the coefficient outside of the parenthesis:

x + 3 = 4(x) + 4(-1) + 2

Simplify:

x + 3 = 4x - 4 + 2

x + 3 = 4x - 2

Subtract x from both sides:

3 = 3x - 2

Add 2 to both sides:

5 = 3x

Divide both sides by 3:

5/3 = x. This is not the answer.

2.

2x - 8 = 7 - 3x

Add 3x to both sides:

5x - 8 = 7

Add 8 to both sides:

5x = 15

Divide both sides by 5:

5x/5 = 15/5

x = 3. This is an answer.

3.

3(x + 2) = 14 - x

Distribute:

3(x) + 3(2) = 14 - x

3x + 6 = 14 - x

Add x to both sides:

4x + 6 = 14

Subtract 6 from both sides:

4x = 8

Divide both sides by 4:

4x/4 = 8/4

x = 2. This is not an answer.

4.

4(x - 1) = x + 5

Distribute:

4x - 4 = x + 5

Subtract x from both sides:

3x - 4 = 5

Add 4 to both sides:

3x = 9

Divide both sides by 3:

3x/3 = 9/3

x = 3. This is an answer.

5.

5 - 2(x + 1) = x

Distribute:

5 - 2x - 2 = x

Simplify:

3 - 2x = x

Add 2x to both sides:

3 = 3x

Divide both sides by 3:

3/3 = 3x/3

x = 1. This is not an answer.

6.

6(x - 4) = 2x

Distribute:

6x - 24 = 2x

Subtract 6x from both sides:

-24 = -4x

Divide both sides by -4:

-24/(-4) = -4x/(-4)

x = 6. This is not an answer.

Answer:

2x - 8 = 7 - 3x

4(x -1) = x + 5

Step-by-step explanation:

2) 2x - 8 = 7 - 3x

   2x + 3x - 8 = 7

       5x -  8 = 7

              5x = 7 + 8

              5x = 15

                 x = 15/5

                x = 3

4) 4(x -1) = x + 5

   4x - 4 = x + 5

4x - 4 - x = 5

     3x - 4 = 5

           3x = 5 + 4

           3x = 9

             x = 9/3

            x = 3

Suppose a researcher compiled a data set consisting of the following variables for a sample of 200 women. For each variable, select whether it is discrete or continuous.

Variable Discrete Continuous
The number of college football games ever attended
The number of sons or daughters
The number of countries ever visited
Pounds of chocolate consumed in the past year
Shoe size
Height in inches
The number of pets currently living in the household

Answers

Answer:

Selecting whether each variable is discrete or continuous:

Discrete Variables:

The number of college football games ever attended

The number of sons or daughters

The number of countries ever visited

The number of pets currently living in the household

Continuous variables:

Pounds of chocolate consumed in the past year

Shoe size

Height in inches

Step-by-step explanation:

The researcher can distinguish a discrete variable from a continuous variable by checking if the value of the variable can be counted or measured.  The researcher can count the value of a discrete variable, and she can measure the value of a continuous variable.  In other words, a discrete variable represents countable objects and a continuous variable represents measurable amounts.

Using variable concepts, we have that the discrete variables are:

The number of college football games ever attendedThe number of sons or daughtersThe number of countries ever visitedThe number of pets currently living in the household

The continuous variables are:

Pounds of chocolate consumed in the past year.Shoe size.Height in inches.

What are continuous and discrete variables?Continuous variables: Can assume decimal values.Discrete variables: Assume only countable values, such as 0, 1, 2, 3, ...

The variables that are countable, that is, discrete, are:

The number of college football games ever attendedThe number of sons or daughtersThe number of countries ever visitedThe number of pets currently living in the household

The ones that can assume decimal values, hence being continuous are:

Pounds of chocolate consumed in the past year.Shoe size.Height in inches.

Answer:

The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.

Let width = x

Let length = x + 4

Perimeter = 48

We can set an inequality for perimeter using the variables.

2x + 2(x + 4) ≥ 48

Solve for x.

2x + 2x + 8 ≥ 48

4x + 8 ≥ 48

4x ≥ 40

x ≥ 10

Substitute this value of x into the variable to get your width and length.

width = 10 cm

length = 14 cm

At a certain store volleyballs with a radius of 4 inches are sold in boxes in the shape of a cube. What is the volume of the smallest box that can hold a

Answers

Answer:

512 cube inches

Step-by-step explanation:

The radius of volleyballs is 4 inches, thus;

diameter of the balls = 2 x radius

                                   = 2 x 4

                                   = 8

The diameter of each ball is 8 inches.

Since the box has the shape of a cube, the smallest box that can hold a volleyball would have its dimensions equal to the diameter of the balls.

So that for the cube,

length = width = height = 8 inches

volume of a cube = [tex]l^{3}[/tex]

volume of the smallest box = [tex]8^{3}[/tex]

                           = 512 cube inches

The volume of the smallest box that can hold a volleyball is 512 cube inches.
